I have a limited supply of my Pi232 Raspberry Pi RS232 boards for sale. I manufactured these for my own projects (see my blog posts), but have more than I need.
They come ready built. Just solder on cables for your plugs/devices.
RS232 RX, TX, 0V solder pins
GPIO 0 to 5 on a small prototype area, with 3v3 and 0v. Handy for LEDs and switches.
UK: £14 (includes VAT & P&P)
EUROPE: £18 (includes VAT & P&P)
Please e-mail me your shipping address, and I will send you an invoice with payment instructions.
OCT 7th : SORRY - SOLD OUT
If you want to manufacture your own, or just look at the design, then you will find it here.
